To all whom am concern} .Be it. lmownthat I, COLE Srmiinna citizen of the United,States,',.and a resident of Indianapolis, county of Marion and State ofIndiana, have invent-ed a .certainnew and useful Steam-Trap; and I do hereby declare y that the following afull, clear, andeXact description thereof,

I fectively seal or referencebeing had to the accompanying.drawinga in which like letters refer to like parts.

The object of this invention is toimprove the construction and operation of vacuum valve mechanisms for steam heaters, radiators and the like, of the type shown in my former Patent No."1,0l5,596dated Jan. 23, 1912. a

The purpose of the improvement is to ef-i prevent the steam fromentcring the vacuum line and thus destroy the vacuum. This object is accomplished by providing the end of the main or air valve on a higher level than the steam and air bypass and by forming a larger constant out air valve than in the said let-in the main or lay-pass. 'ThBIGfOI'G, when the device is put muse, as soon as the air escapes from the top of the trap, water will rise in the cham' her to a higher level than the bypass and the port therein will thus become water sealed and prevent thereafter the-escape of any steam from'the upper part of the device but will permit the escape of air.

Another feature of the invention consists in mounting the seat for the main or air valve vertically adjustable sothat it may be quickly opened and furnish a bypass for cleaning out the device when it is clogged with dirt. V i The full nature of the invention will be understood from the accompanying drawings and the followi g description and claim. V v

In the drawings, Figure 1 is a central vertical section through the-device in idle condition. Fig. 2 is the same in operative condition. Fig. 3 is a part of Fig. 1 showing the parts in position for unclogging the device. Fig. 1 is a section on the line 4l of Fig. 1.v

There is shown in the drawings a cup shaped vessel or casing lO with a top plate 11 secured thereon. the main casing 10 to the vacuum line. a chamber 14 which is in communication with the outlet 13 and in the upper end of l l STEAM-TRAP; 1i Specification of Letters Patent. 1 Patgnted June 15 1915, npplicationfiled bctober s, 1913. Sean Nav'eaesa The inlet port 12 enters while the outlet 13 leads The top plate has in it TEE.

it a nut 15 screws for closing the same and also for supporting the cage .16, the lower end 17 of which, is a seat for the main valve 18." The,l,owerpart of the cage 16 has an annular shoulderat 19 which s rests upon the annular bottom 20of the chamber 14 so that .Whenthe. cage 16 is down and seated, there will be no connection between the chamber ltjand' the chamber 21, below the valve seat 17 excepting through the central opening 22 inthe cage. .The. cage 16 is thus seated normally but .if the device should become clogged, the nut 15 is slightly'unscrewed so as to lift the cage 16 on its seat 20 and thus form a by-pass from the chamber 21 to the chamber 14 whereby the dirt can be cleaned out of the device.

j The main valve 18 is the tapering upper end of a rod.25 which projects in a tube 26 and guided by bars 27 .and 28 near the ends .of said tube 26. The rod 25 projects below the tube 26 and at its lower end is securedto thebottom of the float 30 which is 1 the shape of abucket and located within the casing '10. Inthe bottom of the casing 10 there is an .HPWaIdly extending supporting the rod 25 and float i when. they aren theirlowered 4 position. r The upper'end of the float/loosely surroundsand is guided by a central flange35. extending down from the top plate 11 and v concentric to the tube 26 and rod 25. Therefore, there is a chamber 36 in the upper part of the device and Within the flange 35. From the topof that chamber 36 a p leads to the chamber ence, a by-pass is said by-pass has the reduced portion 46. In valve 18 there is a groove 45 which is larger than the groove46 or the reduced portion of said bypass. This maintains the water column up to the valve seat 17. ber 41 surrounding the float 30.

The operation of the device is as follows:

through the port 12 it will first fill the chan1- ber 41, then the float 30 will rise and the valve 18 will close and thereafter the water There is also a chem-- lug "31 for i ber 41 is filling the air he 119W f through i but air can escape. of operation is because groove &5 and a the float, the air will pass through.

the cage;16 because its port is open and then the air from the float Will pass out through groove 7 the chamber 21 and the'cage 16. After the valve 18 has been elevatedvvith said by-pass, that is roove 45; 'As the Water enters the float-30 it ill rise in thetube'26 and air fromthat tube will pass out through groove 15, As the air passesout from the tube 26 and cha1nber 21 they will float valve 17 and will close,or water seal, the

groove 16 so that no steam can escape a through said port-but air can escape there: there is. no chance Theretore, for steam'to escape into "the vacuum line but there is every possible" opportunity for the air to escape in the vacuum line, "After the deviceis under full operation no steam can escape through the grooves v7&5 and 16, The reason 'for' this mode the large size ofthe i the valve opening 17 as compared with the groove 16 and associated valve opening, will enable the Waterand air, if any, in chamber tube 26 and thus the tube 26*and maintain'a solid column in 16 vvere as large chamber 21. 7 If the groove or larger'fithan the groove 4:5,the pressure i in the two chambers 21 and" '416 would bege'quali'zed so, that there would not be a solid chilies of this patentmav be obtainedrfdrfive cents each, i Washington, D.
